W VIRGINIA: Another team that finds itself trying to steal the thunder in the Big 12 is the Mountaineers. Geno Smith returns as the quarterback after throwing for 4,385 yards, 31 TD and just 7 INT last season. He capped his season by picking apart Clemson in the Orange Bowl for 407 yards, 6 TD and 0 INT. Smith is getting his two favorite targets back in Stedman Bailey (1,279 rec yds, 12 TD) and Tavon Austin (1,186 rec yds, 8 TD), so this WVU offense is going to remain one of the best in the nation. The problem comes on the defensive side of the ball, where the Mountaineers allowed 31.3 PPG in their final seven games. The Big 12 offenses are much more potent than the Big East and WVU's best D-lineman in 2011, Bruce Irvin, was a first round pick in the NFL draft.

TEXAS: After two straight losing seasons in Big 12 play, Texas is confident it can get back to the top of the conference standings in 2012. To do so, the defense will have to lead them there. Despite playing in an explosive offensive conference, the Longhorns finished 11th in the nation in total defense (306 YPG), holding five of their final seven opponents to 20 points or less. Most of this unit remains intact, highlighted by a stellar secondary. There are still question marks on offense, namely QB with the underwhelming duo of David Ash (4 TD, 8 INT) and Case McCoy (7 TD, 4 INT) returning. Texas will be able to run the football again (203 rush YPG) with a bevy of talented backs, most notably Joe Bergeron (463 rush yds, 6.4 YPC, 5 TD) and Malcolm Brown (742 rush yds, 5 TD).

AUSTIN, Texas (AP) - What if No. 8 West Virginia and No. 11 Texas played Saturday and decided not to bring their defenses?

At the rate those two have been giving up big plays for touchdowns, would it really matter?

The Mountaineers (4-0, 1-0 Big 12) needed every one of quarterback Geno Smith's eight touchdown passes in last week's 70-63 win over Baylor that left its defense looking as bad as its offense looked spectacular.

"It was terrible," West Virginia safety Darwin Cook said after Baylor scored nine touchdowns. "It gets you down. We don't like giving up points like that, at all, but you just have to get back up and play the next game. We have to get better on defense."

For Smith, however, the victory continued a blistering start in which he's thrown for 1,728 yards and 20 touchdowns without an interception. He's also completed 83.4 percent of his passes, is averaging 10.22 yards per attempt and leads the nation with a 208.4 passer efficiency rating while emerging as a Heisman Trophy frontrunner.

Texas, though, has a quarterback fully capable of exposing a West Virginia defense that was shredded for 700 yards by the Bears. David Ash, who's second behind Smith with a 184.0 passer rating, threw for 304 yards in a 41-36 win at Oklahoma State on Saturday, making him just the fourth quarterback in Texas history to post consecutive 300-yard games.

The Longhorns (4-0, 1-0) have a 45-0 shutout of New Mexico on their resume, but also have a glaring habit of missing tackles and giving up long touchdowns, trouble signs in a matchup against a quarterback of Smith's caliber.

A unit that was supposed to rank among the best in the Big 12 and the country is now talking about inexperience at linebacker and the middle of the defensive line.

That doesn't explain the missed tackles and broken coverages in a secondary filled with game-tested veterans. The Longhorns have surrendered five touchdowns of 44 yards or longer this season. Smith had four touchdown passes of 39 yards or longer against Baylor just in the second half, and his top receivers - Stedman Bailey and Tavon Austin - have totaled 298.8 yards per game while scoring 17 TDs.

Texas coach Mack Brown says his team missed 12 tackles during the win in Stillwater, giving up 109 yards and two touchdowns. It wasn't clear if he was including the second play from scrimmage when Cowboys running back Joseph Randle juked Texas safety Kenny Vaccaro on a 69-yard touchdown run.

Vaccaro's whiff could hardly be called a missed tackle because he was nowhere close to laying a hand on Randle.

"It is frustrating to give up so many points and big plays," said Texas cornerback Carrington Byndom, who insists the Texas defense hasn't lost the swagger it started the season with.

"We still know the kind of defense we can play," Byndom said.

Texas ranks just 63rd nationally in total defense. The Mountaineers are No. 106.

Brown says the missed tackles are part of the spread offense era of college football. Offenses are designed to put defenders in one-on-one matchups and one broken tackle can lead to a touchdown.

"It's a problem across the country," Brown said.

He also sounds like he's had enough, suggesting Texas may have some new starters on defense against the Mountaineers.

"If we've got four weeks of a guy missing tackles, we've got to start looking at another guy," Brown said without identifying any specific players.

But he's also sensitive about not tearing down his own players too much. Brown still needs a confident bunch to face Smith and the high-flying circus the Mountaineers call their offense.

Brown emphasized what he liked from his defense last week: an interception to set up an early touchdown and holding Oklahoma State to a late field goal that let Texas drive for the winning score with 29 seconds left.

"Nobody will give our defense credit this week. Everybody will bash them. Let's give them credit for what they did," Brown said.

Smith, meanwhile, urged his defense not to lose confidence. If the Mountaineers have to score 10 touchdowns - which they've done three times in the last five games dating back to their Orange Bowl victory over Clemson - again to win, so be it.

"I don't want the defense to hold their heads (down) because it's a team game," Smith said. "Whatever it takes to get a victory is what we'll do."
